I have an Xml document of which parts need to be Hashed for signature.

To get xml subtree I use Namespace aware Document

xml document as image – because SO treats content as SPAM

How do I extract subtree “/EDoc/Signature/Object/QualifyingProperties/SignedProperties”

so it contains inherited namespaces exactly like this?

subtree with correct Namespace information

Tried doing it with XPath:

XPathExpression expr = xpath
                .compile("/EDoc/Signature/Object/QualifyingProperties/SignedProperties");
Node spNode = (Node) expr.evaluate(outdocp, XPathConstants.NODE);

saving spNode to string shows it is missing needed xmlns –
